[Use of lande-edwards membrane oxygenators as artificial lungs].

Lande-Edwards membrane oxygenators were tested as artificial lungs in 6 dogs: the right heart directly perfused the oxygenators during an apneusis of one hour. During such a pulmonary by-pass right ventricular pressure doubles compared to initial value, with a moderate decrease in cardiac output; mean PO-2 rises from 40 to 67 mm Hg and PCO-2 decreases from 54 to 49 mm Hg through the oxygenator.
